The catchment management of reservoirs for drinking water supply not only requires knowledge about the nitrogen discharge of every agricultural field. In order to recommend changes in land use management it is much more important to evaluate its influence to the nitrogen concentration in the reservoir. In order to achieve this the influence of processes that take place during transport must be ...

Electrical discharge machining (EDM) is well established machining technique mainly used to machine complex geometries on difficult-to-machine materials and high strength temperature resistant alloys. In the present research, the objective is to study the shape of the electrode and establish the application of liquid nitrogen in reducing distortion of the electrode during electrical discharge m...

This paper is a first step in analysing how a market for tradeable permits created by an environmental agreement affects the stability of the agreement. I present a model in which the stability implications of (a) the market structure of the permit market and (b) the principle of initial allocation of permits can be analysed. I show that with identical players and an allocation giving every pla...

Nonpoint source nitrogen is recognized as a significant water pollutant worldwide. One of the major contributors is agricultural drainage line water. A potential method of reducing this nitrogen discharge to water bodies is the use of immobilized denitrifying sludge (IDS). Our objectives were to (1) produce an effective IDS, (2) determine the IDS reaction kinetics in laboratory column bioreacto...

Floodplains and river corridor wetlands may be effectively managed for reducing nutrients and carbon. However, our understanding is limited to the reduction potential of these natural riverine systems. This study utilized the long-term (1978–2004) river discharge and water quality records from an upriver and a downriver location of the Atchafalaya River to quantify the inflow, outflow, and infl...

Using the Langmuir probe method, the reactive plasma parameters were studied in different ratios of oxygen and nitrogen concentrations in a DC cylindrical discharge device.The plasma parameters such as plasma potential, electron density and electron temperature wereextracted from the current-voltage characteristic’s curve of Langmuir probe to find the optimum conditions for deposit the oxy...
